A new astronomical analysis suggests that the sky in Vincent van Gogh's The Starry Night may have been inspired by a real dawn over Saint-Rémy-de-Provence, France--not just the artist's imagination.
Researchers led by telescope engineer Elijah Jeong-hyun Kim compared the painting's celestial patterns with historical sky simulations. They propose that the scene resembles the view before sunrise on July 22, 1889, when the crescent Moon, Venus and the Hyades star cluster appeared together in the eastern sky.
The team identified a V-shaped arrangement of five painted stars that closely matches the Hyades, a cluster in the constellation Taurus. Its angle also falls within the range calculated for the cluster's position that morning. The Moon's crescent shape and its placement relative to Venus further support the proposed match.
The researchers, working with colleagues at Kyung Hee University, also compared the painting with a black-and-white drawing Van Gogh made afterward. The stars in that version aligned even more closely with the Hyades. Their findings were published in Scientific Reports.
The interpretation remains a possibility, not proof. A letter from Van Gogh refers to a "study of a starry sky" in June, while the timeline of his work and observations is uncertain. The study therefore does not establish when the painting was completed or whether every detail came from a single night.
The analysis offers a fresh way to connect astronomical observation with artistic interpretation. Future research across science and art history may reveal how closely other celebrated works reflect the skies their creators witnessed.
